Secrets of Rætikon is an action-adventure open world video game developed and published by Broken Rules.

Development began in 2011 and the game was formally announced in July 2013 and followed by alpha and Steam Early Access releases.

[4] The objective is to fly through the Rætikon environment to find its titular secrets, namely by collecting relics to power an ancient device.

The player-character carries the relics past aggressive enemies and treacherous environment, and completes puzzles of reconstructing animal statues from its pieces to access new levels.

[4] He wrote that Rætikon's map design encourages players to think methodically about their path rather than to explore the game as a non-linear open world.

[8] He felt that the animals who steal the game objectives created "busywork", and complained of copious backtracking and the "straight up discourteous" exclusion of an in-game map.

[8] Eurogamer's Jon Denton added that numerous "extremely irritating conflicts" with off-screen animals hurt the game's pacing.

[3] He noted its gameplay influence from Fez and compared its blue shards game mechanics to that of Dark Souls.

[8] Denton of Eurogamer praised the moments where he figured out how to find a shard or alphabet piece, but ultimately found Rætikon "awkward", with "substance did not live up to its style", and causing unjustified and unreasonable frustration.
